Abstract (en)
[origin: WO8200459A1] The purification method of polluted water by dissolved materials which are separable through crystallization, consists in circulating the solution in a heat exchanger where the vaporization temperature is reached, in feeding the solution into a separator in which the vaporization is achieved by expansion. The solution is then fed back to the heat exchanger and the solid materials precipitated by the concentration of the solution are withdrawn from the liquid flow. The apparatus for implementing the method comprises a heat exchanger (14), a separator (16) connected to the exchanger, an extraction device (42) and a means (48) for feeding back the solution to the exchanger.

Le procede d'epuration d'une eau polluee par des matieres en solution separables par cristallisation consiste a faire circuler la solution dans un echangeur de chaleur dans lequel on atteint la temperature de vaporisation, a envoyer la solution dans un separateur dans lequel la vaporisation s'effectue par expansion. La solution est ensuite renvoyee a l'echangeur de chaleur et les matieres solides precipitees par la concentration de la solution sont retirees de la circulation de liquide. L'installation pour la mise en oeuvre du procede comporte un echangeur de chaleur (14), un separateur (16) relie a l'echangeur, un dispositif d'extraction (42) et un moyen (48) de retour de la solution dans l'echangeur.
